Odour-optimised premium recycled pellets directly from contaminated post-consumer material? The effi cient interplayof the innovative ReFresher technology with the proven INTAREMA® TVEplus® machine makes it possible. The un-beatable combination of top pellet quality and odour optimi-sation opens up completely new application opportunities for recycled plastics. In other words: innovative premium products in living space, automotive, design and lifestyle sectors.

INPUT MATERIAL

Remove odours effectivelyA typical problem of household waste: it develops in-tense odours. These are caused on the one hand not only by contaminants adhering to the surface but also by so-called migrated odour substances. The latter are caused by the packaging absorbing the odour of the food, cosmetics or cleaning agents inside it. The substances which migrate like this into the plastic are particularly stubborn.

Removing the entire spectrum of odours again as ef-fectively as possible requires the support of the entire recycling process chain. This includes sorting and wash-ing, plus the mechanical recycling process. Thanks to the effective interplay of the INTAREMA® TVEplus® with the innovative ReFresher technology it is possible to effectively eliminate a considerable amount of these odour substances again.

While the TVEplus® extruder system primarily takes care of the high volatile, low molecular substances, the ReFresher also removes the low volatile, high mo-lecular odour matter.

- Strong contamination- Degree of contamination and moisture vary- Intensive odours: high and low volatile odour substances

Risk of odour through wood, paper and rubberSmall pieces of wood, paper – left behind from labels for example – or rubber and silicone contaminants are potential sources of odour, because in conventional processes these impurities can burn slightly during ex-trusion and in turn transfer the odour to the plastic. The patented TVEplus® extruder system of the INTAREMA® counteracts this odour development in a targeted way.

The challenge of post-consumer packaging(from the household sector, for example)

Gentle melt treatment and high-performance fi ltration= effective odour prevention Gentle melting and a short extruder up to fi ltration – what is good for the melt quality is also effective against additional odour development. This is because the gentle treatment at a low melt temperature and low shear forces means that impu-rities such as cellulose (wood, paper), rubber or silicone fi rstly do not burn and secondly are scarcely reduced in size. They remain large enough to be easily removed by the Laserfi lter – before they can form unpleasant odours. This is intelligent odour prevention, as offered only by the TVEplus® system.

Odour reduction already at the beginning of the process: high volatile residues are eliminatedThe large-volume preconditioning unit ensures a long materi-al residence time at high temperature. In combination with Air Flush technology – which fl ushes the plastic with a continuous, hot stream of air – and the accompanying degassing, this results in the high volatile odour substances being eliminated prior to extrusion. An additional bonus: high residual moisture in the material vaporises.

Powerful extruder degassingThe reverse degassing and fi nal double venting degassing zone at the extruder are particularly effective and remove any gas in-clusions which are still present from the melt. One secret of success of the strong performance here is the homogenisation zone which is located downstream of the fi lter and upstream of the fi nal degassing and brings the melt to the degassing temperature required for the end product.

Thermal-physical cleaning process – without additivesThe ReFresher cleaning process eliminates odours caused by low volatile, high molecular substances. The technology keeps the pellets at the required temperature at which volatile materials can be dischar-ged quickly and in depth. Particularly energy-saving: the ReFresher uses the system‘s own energy from the pellets which are preheated through the extrusion process. Thanks to the ideal, stable process preparationin the INTAREMA® TVEplus® only relatively short residence times are required inside the ReFresher .
